Application filed July 19, 1912. Serial No. 710,355.

To all whom it may concern:

Be it known that I, GEORGE F. HANDLEY, a citizen of the United States of America, residing in Glendale, Long Island, county of Queens, and State of New York, have invented a certain new and useful Improvement in Card Guiding and Holding Devices for Type-lvriting Machines, of which the following is a specification.

This invention comprises an improvement upon structures heretofore invented by Edward B. Hess.

It relates more particularly to card guiding and holding devices for visible writing machines and to 5: special style of means, of the class in which there is a card guide that serves to direct an inserted card or sheet from front feed rolls, and devices extending upwardly across the printing lin said devices comprising a card guiding and holdthe line of print adjacent the printing point and is pivoted so that it may be depressed from in front of the printing line when desired. When in elevated operative position. it is positively locked against lateral strains in either direction and when depressed remains. in normal. lowered position until raised by the operator.

The invention relates particularly to a novel means for locking the guide finger in elevated position and for tripping it for return to depressed condition as will hereinafter appear in detail.

The invention is indicated as applied to a Royal Standard front strike visible writing machine.

In the accompanying drawing: Figure 1 is a partial front elevation indicating the platen, the shiftrail, the card guiding and holding devices and related parts: Fig. 2, a

vertical transverse section; Fig. 3, a detail front elevation; Fig. 4:, a detail elevation of a minor feature of the construction; Fig.

5, a perspective view or a re-action spring adapted to lie-applied to the card holding finger; Fig. 6, a detail front elevation showing a modification; and Fig. 7 is a detail plan view showing left hand movable card holding finger and associated parts.

1 represents the ordinary shift rail; 2, the bottom rail of the transversely movable frame in which is mounted the rotatable platen, and 4 indicates bearing ballsjinterposed between the bottom rail of the irame or carriage and the shift rail. Ordiplaten nary rear feed rolls are. marked 5 and the front teed rolls 6. ()n the top face of the shift rail by means oi a horizontal foot 7 is bolted an upwardly extending plate 8 that 1s shaped to 'grojerct forwardly and then extends upwardly in aplane somewhat in front of the trout printing face of the platen. Below the platen, however, the plate is bifurcated into two arms 9, 10 which first extend laterally and then vertically. Between these two arms is mounted the ordinary type bar guide 11 and ribbon vibrator 12. Extending horizontally between the upper portions of the guide arms 9, 10 is a scale plate 13 disposed at or closely adjacent the lower line of print and which may be adjustable as disclosed in the patent to Edward B. Hess No. 950,326, dated February 22, 1910. Such adjustment is indicated in Fig. 4 in which there is shown beneath the bolt head, in dotted lines, a square aperture 38 in arm 9 and in the center a small dotted circle 39 indicating the shank of the securing screw. The scale is notched at the middle for the passage of type bars it to the printing point and at its ends outside of the upright card arms 9, 10 it is flared outwardly and curled to avoid projecting sharp forwardly. The paper guiding and holding finger so shaped, or of other suitable shape and constructions, lies somewhat closely contiguous to the platen surface and holds and directs cards that are fed up from thefront feed rolls and that are guided by the arms 9, 101 This general arrangement together with a cooperating bail rod 17 carried in the ends of pivoted arms 18 and having rollers 19 thereon coliperating with the surface of the platen above the line of print and beyond the line in which the ends of the guide finger 15 terminates are all old prior to my invention. There is a. similar guide finger disposed at the upper end of the guide arm 9. One or both of these may be pivotedso that they may stand in normal operative position or be depressed from in front of the line of print. It is sufiicient to show one of them as pivoted and ordinarily only the one to the left of the printing point need be so arranged.

Extending laterally from the upper end of the arm 9 adjacent the point at which the scale 13 is attached to it is an integral plate 20 which adjacent the arm 9 is bent or deflected so as to'extend forward at an oblique angle to the axis of the platen as at 20. Upon-this obliquely disposed plate 20 is pivoted the finger which is formed with an extension 22 at right angles thereto and this extension is formed with a cam enlargement 28. that lies flat against the obliquely projecting plate and is pivoted on a stud bolt 24 rigidly fixed in the plate.

The finger 15 is with respect to its extension 22, 23 set at such an angle that when in elevated position it stands opposite the front face of the platen in the same relation thereto as does the fiXed finger 15 Pivoted on a downward extension 25 from the obliquely disposed part 20 of plate 20 is a spring latch 26 provided with a finger'piece 27. A coiled spring 28. surrounding the stud bolt 24 has one end hooked under the latch 26 and the other hooked around the edge of extension 22 forming part of the finger 15*. The reaction of this spring tends to depress the guide finger to the position shown in Fig. in which a shoulder 29 on' the base, portion of the finger 15 rests against an upwardly extending lug 30 on the latch 26. From the shoulder 29, the base plate of the guide finger is formed with a circular edge 31. of suitable radius terminating in a second radial shoulder 32. p The operation is as follows: Assuming the guide finger to be depressed as in Fig. 3,

irator lifts it to elevated position ini in Fig. 1 in which the shoulder 32 passes over the end of latch projection 30, the result being that the finger is locked in operative position against any strain tending to move it to the left. At the same time. the horizontal base edge 15 forming the lower edge of the guide finger proper lies against the straight horizontal upper edsiz-a-of the guide arm See that the guide finger is locked in operative position against strains tending to throw it to the right.

Such strains exerted in either directionl wardly into inoperative position as in Fig.

The Strain q edto raise the g de construct-ion indicated in 1,1a1,sae

the amount of exertion required of the op-. I

orator is trivial.

Fig. 6 shows a modification. The general behavior and construction is quite analogous to what has been described there being-however this distinction. The tripping latch 33 is generally horizontal and is pivoted at 34 intermediate its ends upon an extension of the obliquely disposed plate part 20 extending from arm 9. The base portion 35 of the guide finger 15" is formed with a substantially radial shoulder 36. The reac tion spring-37 is applied substantially as already described being turned around the stud bolt 24 and having one end hooked over the base portion of the guide finger above the stud bolt and the other under the lever between its axis and latch end. 'When the guide finger is in elevated posi tion shown in Fig. 6 lifting of the outer end of the tripping lever will disengage the latch upon its inner end from the shoulder on the base extension of the uide finger thereby allowingthe reaction spring to throw the guide finger to depressed position. A slight lifting strain exerted by the finger of the operator upon the finger 15 restores the parts to position as seen in Fig. 6 in'which the guide finger is positively locked against Y finger turning in a plane oblique to the axis of the platen and having applied thereto a spring that tends to retract it from elevated position in connection with means for positively locking the guide finger against lateral strains in either position when it is elevated.

The form of the invention preferred is that indicated in Figs. 1, 2 and 3since it is deemed to be more convenient for the operator to drop a finger upon the finger piece of the latch lever rather than to lift the free end of the latch lever as is required of the Fig. 6. Iclaim: 1. A paper guiding card holding finger adapted to occupy two positions in one of which it extends across the-line of print and in the other of which it is depressed, a sup.-

-' port upon which the guide finger is pivoted,

rectly eng'a 'ng said shou'lderand a reaction a spring ten g when the latch is tripped to throw the gpidefinger from elevated to depressed -position.,

A card holding and guiding finger adapted to occupy two positions in one of which it extends across the line of print and in the other of which it is depressed from the line of print, said guide finger'having a base extension, a support'upon which it is pivot- -ed, two radial shoulders in such base extensionand a reaction spring tending to throw the guide finger from' elevated to depressed position and a tripping latch that engages one of said shoulders to limit downward movement of-the guide finger and'the other of said shoulders to-positively lock the guide finger in elevated position.

3. A card guidingand controlling finger adapted to occupy a position in which itextends across the line of print and; also a position in which it is lowered from-the" line ofprint, said finger being provided with a .base extension, a support upon which such base extension is pivoted, a reaction spring tending to throw the gulde finger from 'ele vated to lowered position and a downwardly movable detent latch adapted to positively lock the guide finger in elevated. position.

4. A card guiding and controlling finger adapted to occupy two positions, in one of which it lies across the line of print and in the other of which it is lowered from the line of print combined'with an upright card guiding arm having a lateral extension adjacentits top, a base extension forming part of the card guiding finger and by means of which it is pivoted to said lateral extension from thecard guiding arm, a tripping latch also pivoted upon saidlateral extension and a spring applied to the latch and also to the guide finger and a projection of thebase' extension of the guide finger cooperating with the latch whereby when the latch is manipulated the guide finger is tripped and the spring-allowed to throw it to lower position but when the finger is elevated the base is locked with the finger in operative position.
